I am trying to set up subscriptions in a premium capacity or paginated reports with paramters, but every time I try to save the subscription, all the parameters that are configured (most are default) disappear from the subscription. I don't even have a section to update the parameters at all. I've attached a screenshot of an interesting error that pops up after attempting to save the subscription with the parameters:

To reproduce this, steps are pretty simple:
- Have a paginated report with parameters that can be null
- Execute the paginated report in the service
- Create a subscription for that report with the parameters set to the default value (some are null and some are not)
- Check the subscription and you will see that no parameters are present in the subscription
One thing that makes me suspect this is a bug is that there are older subscriptions that have the same exact steps taken above from 1 month ago that are working as expected. We also created another subscription for a different report that does not take a null parameter and that report subscription worked as expected.
